After war broke out in the former Yugoslav republic of Croatia in the fall of 1991 and in Bosnia in April 1992, Arkan and his units moved to attack different territories in these countries. In Croatia, the Tigers fought in various locales in SAO Eastern Slavonia, Baranja and Western Syrmia.

Ražnatović and his "Tigers"

Paramilitary units are responsible for some of the most brutal aspects of ethnic cleansing. Two of the units that have played a major role in the ethnic cleansing campaign in BiH, the Chetniks associated with Vojislav Šešelj and the Tigers associated with Zeljko Raznjatovic (Arkan), have been active in the Republic of Serbia as well...Arkan's Tigers have staged military training exercises allegedly designed to intimidate Albanian residents in Kosovo.[2]

In autumn 1995, Arkan's troops fought in the area of Banja Luka, Sanski Most and Prijedor where they were routed. Arkan personally led most war actions, and rewarded his most efficient officers and soldiers with ranks, medals and eventually the products of the lootings. The Serb Volunteer Guard was officially disbanded in April 1996. Besides Arkan, a notable member of the Guard was his right-hand man, Colonel Nebojša Djordjević, who was murdered in late 1996. Another notable member was Milorad Ulemek, who is now serving a 40-year sentence for his involvement in the assassination of Serbia's pro-Western prime minister Zoran Đinđić in 2003.[citation needed]

Several Golden Dawn members participated in the Bosnian War in the Greek Volunteer Guard (GVG), which was part of the Drina Corps of the Army of Republika Srpska. A few GVG volunteers were present in Srebrenica during the Srebrenica massacre, and they raised a Greek flag at a ruined church after the fall of the town.[3] Spiros Tzanopoulos, a GVG sergeant who took part in the attack against Srebrenica, said many of the Greek volunteers participated in the war because they were members of Hrisi Avgi.[4] Chrysi Avyi members in the GVG were decorated by Radovan Karadžić, but — according to former Chrysi Avyi member Charis Kousoumvris — those who were decorated later left the party.[4]

The ICTY charged the Serbian Volunteer Guard, under the command or supervision of Željko Ražnatović of:[5]
